UK's mobile carrier Orange and renewable energy designers GotWind partnered to develop the Sound Charge T-Shirt. As the name suggest the T-Shirt converts sound into electric energy. The T-Shirt uses a modified piezoelectric film panel absorbing the sound pressure waves into electric energy.

Usually found in modern hi-fi speakers, an A4 panel of the modified film is housed inside a t-shirt which then acts much like an oversized microphone by ‘absorbing’ invisible sound pressure waves. These sound waves are converted via the compression of interlaced quartz crystals into an electrical charge, which is fed into an integral reservoir battery that in turn charges most makes and models of mobile phone. As the ‘device’ is worn, a steady charge is able to be dispensed into the phone via a simple interchangeable lead which fits most handsets.
The Sound Charge will be live tested at the Glastonbury Music Festival. If you ever attended a concert you can imagine that this actualy might work well.
Orange estimates that the Sound Charge T-Shirt can generate enough energy to charge a smartphone at the Glastonbury Festival. Watch the video below to learn more about Sound Charge.
